Research on the health effects of grapefruit seed extract is limited. What's more, the American Botanical Council published a report stating that some grapefruit seed extract products tested in available studies may contain undisclosed ingredients. In some cases, those ingredients may be responsible for the tested products' health effects.
In the 2012 report, American Botanical Council investigators found that many grapefruit seed extract products on the market today contain synthetic chemicals (including preservatives and disinfectants) that aren't listed on their labels. Those chemicals include benzethonium chloride, a compound found in many cosmetics, ointments, and first-aid antiseptics.
